Some people (Yahoo, CNN, etc.) locate "european-flavour" servers in Europe,
"cantonese-style" servers in Hong Kong, and so forth.   Some people use 
Akamai and their competitors, which seem to be locating stuff in various
places around the world.  Most content just comes from wherever it happens
to be hosted, and often enough that's somewhere in California.  Works great.
